I purchased middle October Brand New, the latest revision of the EOTech 551. I was going to use it in conjunction with another scope and an A.R.M.S. mount and my disastisfaction with the A.R.M.S. has me scrapping the projectI also purchased a Falcon 4" mounting platform (picatinny rail) with adapters and hardare to bolt onto a float tube- a very trick set-up. This is still in the bag. The EOTech is in the box with all papers manual etc. If you can tell any of this from brand new I'll take it back. $355 shipped FedEx 3-Day for both, add $10 for PayPal and I'll get it out quickAugust at gunboy@sbcglobal.netIf you need pics e-mail me
